What is the electron domain geometry and bond angle of a molecule with 6 domains?
Octahedral; 90 degrees
A molecule with 6 domains can have different electron domain geometries depending on the type of domains present. However, one possible example of such a molecule is sulfur hexafluoride (SF6).
In SF6, there are 6 electron domains consisting of 1 sulfur atom and 6 fluorine atoms. The electron domain geometry is octahedral with a bond angle of 90 degrees. This means that the 6 domains are arranged symmetrically around the central sulfur atom, forming a shape that resembles two square-based pyramids attached at their base.
Each of the fluorine atoms is bonded to the sulfur atom through a single covalent bond, and there are no lone pairs on the central sulfur atom. This results in a true octahedral geometry with all bond angles measuring at 90 degrees.
Overall, it is important to note that the electron domain geometry and bond angle of a molecule with 6 domains will depend greatly on the type and orientation of the domains present, and so it is important to determine each molecule’s specific arrangement before assigning a geometry.
